nature : molecular compounds were all negative -- and the larger atomic hydrogen atoms connected again and may have the same elements or other elements of the other negative -- the larger atoms connected, the resulting bond, called hydrogen bonds . It takes the form of the atomic hydrogen bond (such as N, O, F, etc.), with a smaller radius of the atom and not shared electronic right. Water, ethanol, acetic acid and other elements as well as the association of protein and nucleic acid molecules, three-dimensional structure, and the hydrogen bond. Hydrogen bonds with different common bond, bond length and longer keys can be less vulnerable to sabotage. The presence of hydrogen bonding, the general nature of the compounds have significant impact, such as higher melting point, boiling point and solubility.
